Teams are one of the most important elements of an organisation. Sometimes, a team works well together, and other times, they struggle. Therefore, it is important to identify the practices that help to shape optimal ways of working and unlock performance.

A team will not be productive by chance, or by default, let’s walk through some of the practices and ideas that can help to foster productivity from day one.
